Hi. I recognized this weekend that I started to have a slight dull aching pain in my left testicle and groin area. It is not severely painful, but does cause discomfort. There has been no trauma to the area, with no fever or severe swelling. I did, however, just get off of a 3 day fast, but I dont know if this may have anything to do with it. Im a little nervous, as cancer does run in my family. How long do I give it befoe I make an appt with urologist? Thanks
